    The QCD static energy at NNNLL

    Get PDF
    We compute the static energy of QCD at short distances at next-to-next-to-next-to leading-logarithmic accuracy in terms of the three-loop singlet potential. By comparing our results with lattice data we extract the value of the unknown piece of the three-loop singlet potential.Comment: 25 pages, 16 figures. v2: Incorrect files for figure 7 replaced by the correct ones.

    Extraction of alpha_s from radiative Upsilon(1S) decays

    Full text link
    We improve on a recent determination of alpha_s from Gamma(Upsilon(1S)-->X gamma)/Gamma(Upsilon(1S)-->X) with CLEO data by taking into account color octet contributions and avoiding any model dependence in the extraction. We obtain alpha_s(M_Upsilon(1S))= 0.184+0.015-0.014, which corresponds to alpha_s(M_Z)=0.119+0.006-0.005.Comment: 11 pages. v2: One reference added. v3: Minor modification in an error estimate.

    Towards a new healthy and sustainable food model. Transition of food policies: from “C40 to Barcelona”

    Treballs Finals de Grau de Nutrició Humana i Dietètica, Facultat de Farmàcia i Ciències de l'Alimentació, Campus de l'Alimentació de Torribera, Universitat de Barcelona. Curs: 2019-2020. Tutor: Itziar de Lecuona[eng] The concern for sustainability has risen in recent years because of the harmful consequences we are suffering. Although vegetarian dietary patterns have been widely adopted in order to mitigate the environmental footprint, the possibility for other diets to have similar outcomes has been highly discussed. The transition of the food system model towards a healthier and more sustainable one is urgently necessary and while meeting the committed goals of COP21 and 2030 Agenda is still possible. An integrative and multisectorial approach will be efficient if the established actions tackle issues across the food supply chain at all levels, from food production to food consumption. At the consumption extent, feeding the 2050 expected population is possible if a healthy and sustainable diet (omnivorous dietary patterns with very limited animal source content) is implemented globally with scope for adaptation to regional culture and preferences. Aligned with this mission, Barcelona is a pioneer city in the national context by being committed to international organizations, such as C40 Cities, to reduce their impact on climate change and apply measures based on strong and high-quality evidence such as a reduction of red meat in school canteens.[cat] L’empitjorament del canvi climàtic en la última dècada ha fet que la preocupació per la sostenibilitat s’hagi convertit en un tema emergent essent la implementació d’una dieta vegetariana, una de les modificacions més comunes. Tot i així, estudis recents corroboren que no és necessari eliminar les fonts d’origen animal per aconseguir un impacte mediambiental similar al de les dietes vegetarianes. Tanmateix, la transició cap a un sistema alimentari més saludable i respectuós amb el planeta s’ha de realitzar amb urgència ja que encara és possible assolir els objectius fixats pel COP21 i l’Agenda 2030. El nou sistema ha de destacar per la integritat entre els diferents sectors i és per això que les accions requerides per tal que el procés sigui eficaç han d’estar adreçades a tots als fases de la cadena alimentària des de la producció fins a la distribució. Serà possible alimentar la població mundial estimada al 2050 si s’adopta una dieta omnívora modificada (amb un contingut molt reduït de productes d’origen animal) que a part de ser saludable també és respectuosa amb el planeta. Barcelona ha estat pionera, en aquesta mateixa línia, a nivell nacional pel seu compromís amb diverses organitzacions mundials, com és la C40 Cities o amb els objectius de les Nacions Unides, per tal de reduir la seva petjada ecològica. Això s’ha aconseguit a través de la implementació de diverses normatives, basades en evidència científica d’alta qualitat d’entre les quals destaca la reducció de la carn vermella als menjadors escolars

    EFORMING THE ELECTORATE: PATTERNS OF TECHNOLOGY USE

    Get PDF
    This paper discusses research-in-progress on a longitudinal study of technology usage by incumbent members of the U.S. Congress on their official Congressional homepages to “routinely” communicate with the public and with their constituencies as well as technology usage on campaign homepages for the purpose of political campaigning. By examining the types of information technologies embedded on and linked to from both types of homepages, we propose to track technology usage over time in order to study the diffusion and adoption of information technologies within the political arena. Drawing on diffusion of innovation and institutional isomorphism as our theoretical framework, we propose that examining patterns of diffusion of three categories of information technology – Web 1.0, Web 2.0, and Social Networking technologies – will provide us with insights into the changing nature of political communication strategies enabled by information technology, as well as insights into factors underlying institutional technology diffusion

    SARAH GAVRON’S SUFFRAGETTE: SHAPING GENDER EQUALITY IN WOMEN’S RIGHT TO VOTE ISSUE

    This study aims to reveal the women struggle in fighting for human rights, especially for women done by women characters in a movie entitled Suffragette, directed by Sarah Gavron. As women who live the life whereas the government of the country is dominated by men, it is hard for women to participate in the government. Based on that, some research problems of this study are related to: (a) how society treat women especially related to women's working condition; (b) how is the oppression of women depicted in the movie; and (c) how is the First Wave of Feminism affects to the women movement. To analyze the movie, this study will use the conception of women's right by Mary Wollstonecraft and a perspective of First Wave of Feminism. The result of this study showed that the female characters want to shape women and men equality in the case of women’s right to vote as civil right. They wanted an equality between the men and the women, being appreciated, and had security from the country by become participant of government.Keywords: Suffragette, Gender Equality, Right to Vote, First Wave of Feminism, Mary Wollstonecraft
